RJ45 transceiver modules support different Ethernet speeds by pairing the appropriate SFP or SFP+ host interface with copper Ethernet technology, including 1 Gbps and 10 Gbps options. Cable type and distance vary by module, with examples supporting Cat 5 cable up to 100 meters, Cat 6A cable up to 80 meters, or twisted-pair cable up to 100 meters, so select a module that matches the switch port, cabling, and project distance.

RJ45 transceiver modules work with network switches and compatible networking equipment that provide SFP or SFP+ ports, with the module type matching the slot’s speed and interface requirements. SFP modules support up to 1 Gbps over RJ45 Cat 5 cabling, while SFP+ modules support 10 Gigabit Ethernet over compatible twisted-pair cabling, with the supported distance depending on the module and cable.

Use RJ45 copper Ethernet cabling that matches the module’s interface and rated speed, such as Cat 5 for up to 1 Gbps or Cat 6A for up to 10 Gbps. Confirm that the switch has a compatible SFP or SFP+ port, and keep the cable run within the module’s supported distance, which may range from 80 to 100 meters.

Choose an RJ45 transceiver module with SFP+ support when compatible switch ports and network equipment support SFP+, and the installation calls for higher-speed Ethernet over twisted-pair cable. Choose an SFP module for compatible SFP ports and projects that use standard RJ45 Ethernet connections at up to 1 Gbps.
